9. NFT land purchase and mining system

In Second City, users can mine CITY tokens once a day on the Land NFT they own by constructing a building. The game provides two methods for mining: direct mining by the owner and mining on others' NFTs.

1. Owner Mining

   • Users can log in and click on their owned building to mine 15 CITY tokens per day.

   • Users can easily warp to their owned lands without being restricted by the subway system.

   • The building owner can manage the building, check the guestbook, communicate with friends, and modify building advertisements.

2. Mining on Others' Buildings

   • Users who do not own a building can mine on others' buildings.

   • By clicking on another user's building and pressing the mining button, users watch the set advertisements, mine 1 CITY token per building, and automatically reward the building owner with 14 tokens.

   • The building can't be mined on for the rest of the day after this action.

   • Users can mine on a maximum of 15 different buildings per day.

3. Land NFT Purchase

   • Second City plans to sell empty land in different regions, and any user can purchase these lands.

   • Users freely explore the game, discover vacant land, and can instantly buy the land if they like its location.

   • Landowners can easily purchase more land by mining more CITY tokens, while those without Second City's Land NFT can explore and mine on buildings owned by other users. This provides everyone with the opportunity to purchase Land NFTs.

   • Adjustments to mining levels based on the sales of NFT lands are possible, ensuring flexibility in response to the game's dynamics.

This economic model encourages active participation from both landowners and users exploring the city.
